Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many projects being delivered through the infrastructure pipeline relate to national defence; and what proportion of all infrastructure pipeline projects they represent.

The current Infrastructure Pipeline, updated on 9 March 2026, includes one aggregated line on defence infrastructure spending. Once the Defence Investment Plan is published, project level detail we be available and included.

The Infrastructure Pipeline line represents the total 10 year capital and resource committed Infrastructure Plan expenditure at SR25 excluding Aquatrine and Utilities spend. This is reported as £3.51 billion of planned expenditure. It is important to note that the Infrastructure Pipeline includes physical infrastructure and construction only, and therefore is not representative of all capital spending by the Ministry of Defence.

The July 2025 publication of the Pipeline included 71 projects and 5 programmes in the defence sector. At the time of the July publication, this represented £20.4 billion of expenditure.

Following the publication of the Defence Investment Plan, we expect to reflect all Defence projects meeting our inclusion thresholds in future iterations of the Pipeline
